The device (1) has a sound-reflecting element (4) i.e. round disk, arranged at a predetermined distance (A) to an edge (6) of a cup (2) of a clarinet. Diameter of the sound-reflecting element is larger than diameter of a surface at the edge of the cup. A surface (5) of the sound-reflecting element is turned towards an outlet of the cup. The outlet of the sound-reflecting element is formed in round, polygonal and oval shapes in a plan view. The surface of the sound-reflecting element is formed in parabolic, hyperbolic, concave and convex shapes.
